Description
Receiver Output. If A > B by 200 mV, RO is high; if A < B by 200 mV,
RO is low.
Receiver Output Enable. A low level enables the receiver output. A high
level places it in a high impedance state. If RE is high and DE is low, the
device enters a low power shutdown mode.
Driver Output Enable. A high level enables the driver differential A and B
outputs. A low level places it in a high impedance state. If RE is high and DE
is low, the device enters a low power shutdown mode.
Driver Input. With a half-duplex part when the driver is enabled, a logic low
on DI forces A low and B high; a logic high on DI forces A high and B low.
With a full-duplex part when the driver is enabled, a logic low on DI forces Y
low and Z high; a logic high on DI forces Y high and Z low.
Ground.
Noninverting Driver Output.
Noninverting Receiver Input A and Noninverting Driver Output A.
